I bought an AMD GPU before and the experience was so horrible that it's deterred me from ever buying one again.
I never knew how good I had it with Nvidia until I tried AMD. The main issue? Drivers. AMDs drivers were abysmally shit. I never had to 'choose' specific versions of Nvidia drivers to get them to work. I did with AMD, and some features would work while others would break depending on the version.
Ended up returning it because it was that bad.
